!914 Twin HD Cannon ball request

[Lonnie]

To say that I am impressed with the work Joe is putting into this bike is an understatement. Thanks for documenting this in photos for our benefit.

For those who don't know, Matt Olson is also documenting the work on his ride for the Run on pre16scramble.blogspot.com.

Both guys are putting a tremendous amount of time in on these bikes. I hope to be able to see them at the Wheels Through Time museum at that stop on the Run.

Joe,

You are a true artisan! Thanks for sharing your gift with us.

Joe, what kind of brake linings are you using? Will that brake lock up when a deer jumps out in front of you coming down a mountain pass? Can the fork handle the extra power of the brake? Just curious as I am thinking of putting a twin leading shoe Norton Manx brake on a Norton girder fork.

Brake linings are on order and should be here today. I am not sure what the brand is, if they work well I will not look any further otherwise... As far as locking up, I am unsure of the power of this brake although it should be strong enough to do the job after all it came off a racing dirt bike of similar size and weight. The fork is a 1916-23 unit actually a 1923 J model fork with the accessory booster spring installed. The auxiliary springs will provide the required resistance for support braking loads. The fork rigidity itself remains questionable and plans are in phase for an external stiffener of the rigid fork. As far as the disc brake originaly intended for this bike, well,,, I change my mind besides this assembly once finished with nichol plating on the right side spoke flange, spokes and linkages along with the gray paint and possibly pinstriped cooling fins will have a great look. Thanks for following along and participating in this forum I do enjoy the company.

Sounds good Joe. You are probably aware Brough used a Harley 'bottom link" fork and George Brough raved over it's stability. However it has some inherant weaknesses and if you look at Brooklands and other period bikes using these forks quite often they stiffened the rear leg with a gusset. ( you have seen the way I copied this idea for my Koslow for a different reason) and of course the evolution to the I beam rear leg was an indication that Harley knew this was an area that needed an upgrade. I am sure when you finish with it , it will be a work of art as is everything you do.

Been wondering when the videos would surface. Nice job with a new camera. I'm a mostly retired machinist / low grade tool maker & appreciate what you are doing. I did recognize the green shift knob on the 48 dualie that I sold you a few years ago at Oley. Really enjoying all the coverage. Hope to be able to catch part of the cannonball run along the way.

Sorry I got things out of sinc. I met this to so right after the videos on page 33

I'm not a teens guy, but my guess is they are from the Club Casting era. I can reproduce them if you want to send a sample. 2 samples could get a better price.

The 48 "dualie" has more parts than the green shift knob from your collection, the greenie is special. I must thank you again for bringing it to Oley for me.
I have not posted much this week but am working on some interesting stuff with ammeter video action of more CNC operations, perhaps tonight I will get caught up on my posting.
The brake anchor stuff did what I wanted it to do, conceal the anchor, but I sent it to the scrap pile for a more conventional method. Some times thinking out of the box will put you into another box that just does not work. The brake backing plate rotated around the axle near 90 degrees through the entire travel of the fork so it had to be eliminated, to much cable action is not good.

The high road

Replacing the current brake anchor design and parts for a more conventional system became necessary. With the first design the brake cable would whip around while the suspension was in action. This weekend focus was on devising a new system for holding the brake backing plate in place while under operation and braking. I did not want to hang a anchor on the fork leg as this will require slight modification/welding to the fork main leg.
A devise was designed that will attach to the brake backing plate and provide a location for the shackle to join with a "new shackle anchor plate" and fork leg by conventional means. Much of the difficulties are the compounding interference when introducing the new shackle anchor plate with the dual leading shoe linkage, the stay boss location on the plate and fork rocker studs. In other words the limited amount of space to fit everything in its functioning location. This brake plate did not lend itself well for this application.
The linkage for the dual leading shoe brake plate had to be reversed and modified to clear the fork leg. This operation requires reworking and mixing of other Honda brake levers that I found laying around. I will attempt to load You Tube Video and photos of in process operations of the making of the new brake parts. There is some fascinating machine work involved for those who are not familiar with CNC equipment.

Chips are flying, safety glasses required.

Following are some of my amateur You Tube videos that demonstrate what I have been developing the last few days. A new brake stay had to be devised.
The speed at which the machine is operating is true actual run time. I sped up operations to keep things interesting and not put anyone to sleep.
Aluminum Sun wheel rims and carbon steel spokes are on order so this brake must be finish off soon in order to build the wheels. When the rims and spokes arrive they will be sent to plating and painting. Afterwards I will lace up the spokes and installed the wheels on the bike, expect three weeks or more for this to take place.

I'm a definitely off on timing with these but here's the last batch....

[jurassic]

so ,now were down to about 5 months,you really going to have this thing done or not? tick,tock , tick,tock

Have faith things are happening . Once all the details are worked out it will come together sooner than you think.

If at first.........

I have had a week full of activity with work and motorcycle projects. The front brake is nearly complete with many new and revised parts fabricated this week. One of the challenges, when tightening the front axle the front brake backing plate must remain free to rotate a small amount. Unlike the original application XR 500 R Honda where the brake plate was fixed to the fork without the ability to rotate on the axle. The backing plate was part of the Honda system used to pre-load the inner races of the wheel bearings. With the light weight intention of this part there is not much available material to remove. When modifications become necessary to adapt the brake to a springer fork were different mechanical requirements present themselves caution is priority so as not to weaken the parts being modified and the inverse, make the new adapters strong enough to handle their responsibilities.
The brake plate anchor is now a shackle in the same fashion as all Harley's from the 1928 through the end of springers in fifty something where the Hydraglide fork took over the beloved springer's job on the Servy Car. A weld on bracket is in process now and will be attached to the main fork leg to secure the brake shackle. Perhaps tonight I will bring all of you up to date with photos and videos, for now I am off and running.

Following are a photos taken while fabricating the brake stay that will be welded to the main fork leg. The part was made from a solid piece of cold rolled steel and will resemble the unit on a late model springer when completed. Once the part was machined close to net size I took a ride over to see my ole friend Mark the spark for some surface grinding. These grinding guys are strange, first diamonds are used to sharpen and form a bunch of rocks then they beat steel with those little rocks until the desired shape and size are achieved, go figure. Mark is a specialist in the grinding trade and will run circles around most grinder hands plus he is always's good for a converstaion.
We first used a carborundum (sp?) stone to ruff in the shape of the wheel and then used a radius dresser to finish form the grinding wheel. Next was to fixture the work piece into a precision vise and grind away to form a nice transition with all surfaces flowing tangent to adjoining surfaces.
I spoke with Mike from Barnett Clutch today, he is making for me a special set of clutch plates for my Freewheel Clutch. I have been using Barnett Clutches for 33 years they are the best in my little world.
Once we pulled a full size Ford out of a muddy ditch with two big twins (a 63 pan and a 66 shuv) both equipped with the old three and a half plate Barnett Clutches. This was car was buried to the frame and was not coming out on it own accord. When out of the mud and ditch it then had to be pulled up a hill back onto the road surface. My buddy that ditched the car is legally blind and should not be driving in the first place.
I am watching the mail every day this week for Buchanan wheels and spokes.
Cory! wake up
